    go: Update usage of TARGET_AIX to TARGET_AIX_OS
    
    TARGET_AIX is defined to a non-zero value on linux and maybe other
    powerpc64le targets.  This leads to unexpected behavior such as
    dropping the .go_export section when linking a shared library
    on linux/powerpc64le.
    
    Instead, use TARGET_AIX_OS to toggle AIX specific behavior.
    
    Fixes golang/go#60798.

            * go-backend.cc [TARGET_AIX]: Rename and update usage to TARGET_AIX_OS.
            * go-lang.cc: Likewise.
